Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 19470, here are decompositions:

7 + 19463 = 19470
13 + 19457 = 19470
23 + 19447 = 19470
29 + 19441 = 19470
37 + 19433 = 19470
41 + 19429 = 19470
43 + 19427 = 19470
47 + 19423 = 19470

Showing the first eight; more decompositions exist.
